Congrats on the new gig! You should be oriented to the tasks at your facility, including admissions. That being said, for our facility we take report before getting the patient, unless the patient comes up with the RN from ED/surgery/PACU/wherever. We get the room ready which includes zeroing the bed (we weight pts in bed), welcome packet ready, check to make sure supplies are ready. When pt comes to floor we do a basic admission which documents items brought to the hospital/what got sent home, ht/wt, initial set of vitals, etc. we do a complete pt history, including previous surgeries, pertinent family hx, med reconciliation, allergies, depression assessment, social hx, pertinent information such as current or hx of abuse, etc, etc. a complete assessment is performed. Check lines and place any new or extra lines as needed, check orders (I check dosing and such against their med rec too as this has been an issue in the past), label lines and bags. I always chart a note about how the patient presented upon arrival, including vent/BiPap settings, generally how they looked, LOC...just a quick snapshot of how they came to me.
We also always go over room policies (yeah, no smoking etc), when the docs will be around, what their diet order is and when they can order, if they are NPO I explain why and make sure family understand this as well if they are present, things like that.
Hope that helps! I was VERY slow with admissions as the start, but after you do a few you get quicker at them (like anything else!). Good luck to you in your new job!!
